The move comes as police in west Wirral pledge to clamp down on youth disorder with extra patrols and arrests.

Heswall neighbourhood inspector, Mike Jarman, said last night: "The plan involves identifying who these people are, what they are doing and, where necessary, where they are buying alcohol."

Speaking after an incident in which broken glass was left strewn across a children's play area in Mill Hill Park, Irby, he said: "We are also urging responsible adults to support this initiative. Often alcohol is involved and it is purchased on behalf of the teenagers by a passer-by. This must stop."

Amid the foul language included in the graffiti at Spital Station were bizarre phrases such as "Artism is our weapon" and "I'm at war".

But yesterday Coun Cummings declared war on the vandals, saying: "Every available inch of space has been covered and we have to act to put an end to this needless waste of public money.

"Spital is a lovely residential area and these yobs are making life miserable for the families who live and work here.

"We are getting fed up of people coming in along the line and causing disruption.

"Once these yobs are caught they should be made to pay for all the damage which they have caused - and, if that means parents having to pay, then so be it."

Police Constable Joan Moore, of British Transport Police said: "Spital station is totally covered in graffiti, it is everywhere. There is extensive damage to the interior as well as signal boxes and the outside walls.

"It is vital the public support our attempts to track these vandals down, and I would urge anybody who witnesses vandalism at railway stations to call us on 0800-405040." Deputy managing director of Arriva Trains Merseyside, John Skinner, said: "We take the matter of vandalism very seriously.

"It makes the network look bad, it makes life uncomfortable for passengers, and it costs us money."
